Abstract

A display device includes a plurality of pixels that is arrayed in a first direction and a second direction. Each pixel includes; a first sub-pixel, a second sub-pixel that is disposed to be adjacent to the first sub-pixel in the first direction, a third sub-pixel that is disposed to be adjacent to at least one of the first sub-pixel and the second sub-pixel in the second direction, and a light shielding portion that is disposed corresponding to the position on which the third sub-pixel is disposed, so as to limit a viewing angle of the third sub-pixel in the first direction.

Claims (59)

1. A display device comprising:

a plurality of pixels that is arrayed in a first direction and a second direction,

wherein each pixel includes;

a first sub-pixel,

a second sub-pixel that is disposed to be adjacent to the first sub-pixel in the first direction,

a third sub-pixel that is disposed to be adjacent to at least one of the first sub-pixel and the second sub-pixel in the second direction, and

a light shielding portion that is disposed corresponding to the position on which the third sub-pixel is disposed and including a first part that is disposed on a boundary between adjacent pixels in the first direction and a second part that is disposed within the third sub-pixel in one pixel, so as to limit a viewing angle of the third sub-pixel in the first direction, and

wherein the light shielding portion is not disposed between the first sub-pixel and the second sub-pixel.

2. The display device according claim 1 ,

wherein the third sub-pixel is disposed to be adjacent to both the first sub-pixel and the second sub-pixel in the second direction.

3. The display device according claim 2 ,

wherein a width of the light shielding portion in the second direction is less than an opening width of the third sub-pixel.

4. The display device according claim 2 ,

wherein the first sub-pixel includes a first color filter that transmits a first color light,

wherein the second sub-pixel includes a second color filter that transmits a second color light,

wherein the third sub-pixel includes a third color filter that transmits a third color light,

wherein a color separation is mutually performed on the first sub-pixel and the second sub-pixel in the first direction and performed on the third sub-pixel in the second direction by the first color filter and the second color filter, and

wherein a color separation is performed on the first sub-pixel and the second sub-pixel in the second direction by the third color filter.

5. The display device according claim 2 ,

wherein the sizes of the first part and the second part are different from each other.

6. The display device according claim 2 ,

wherein the second part is provided on a center portion in the third sub-pixel in the first direction.

7. The display device according claim 2 ,

wherein the second part is provided on a position different from the center portion in the third sub-pixel in the first direction.

8. The display device according claim 7 ,

wherein, in one pixel, a first pixel area and a second pixel area are formed in the third sub-pixel with the second part as a boundary, and

wherein viewing angle characteristics of the first pixel area and viewing angle characteristics of the second pixel area are different from each other.

9. The display device according claim 2 ,

wherein the light shielding portion has a rectangular shape, an elliptical shape, or a circular shape.

10. The display device according claim 2 ,

wherein the first sub-pixel includes a first light emitting element that emits the first color light,

wherein the second sub-pixel includes a second light emitting element that emits the second color light,

wherein the third sub-pixel includes two third light emitting elements that each emit the third color light, and

wherein, in one pixel, the two third light emitting elements are separated by a gap located at a position corresponding to a position on which the second part is provided.

11. The display device according claim 10 ,

wherein, in the second direction, a width of a respective third light emitting element and a width of the light shielding portion are different from each other.

12. The display device according claim 1 ,

wherein the first color light is emitted from the first sub-pixel,

wherein the second color light is emitted from the second sub-pixel,

wherein the third color light of which a wavelength is shorter than that of the first color light and the second color light is emitted from the third sub-pixel, and

wherein, in the second direction, an opening width of the third sub-pixel is less than an opening width of the first sub-pixel and an opening width of the second sub-pixel.

13. The display device according claim 1 ,

wherein each pixel further includes a fourth sub-pixel that is disposed to be adjacent to the first sub-pixel in the second direction,

wherein the third sub-pixel is disposed to be adjacent to the second sub-pixel in the second direction and is disposed to be adjacent to the fourth sub-pixel in the first direction, and

wherein the light shielding portion is disposed around the fourth color filter so as to include a boundary portion of the first sub-pixel and the third sub-pixel.

14. The display device according claim 13 ,

wherein the light shielding portion limits the viewing angle of the third sub-pixel in the first direction and limits the viewing angle of the fourth sub-pixel in the first direction and the second direction.

15. The display device according to claim 1 ,

wherein the first portion part is discontinuous with the second -portion part.

16. The display device according to claim 1 ,

wherein the light shielding portion is contained within the third sub-pixel.

17. An electronic apparatus comprising:

a display device in which a plurality of pixels is arrayed in a first direction and a second direction,

wherein each pixel includes;

a first sub-pixel,

a second sub-pixel that is disposed to be adjacent to the first sub-pixel in the first direction,

a third sub-pixel that is disposed to be adjacent to at least one of the first sub-pixel and the second sub-pixel in the second direction, and

a light shielding portion that is disposed corresponding to the position on which the third sub-pixel is disposed and including a first part that is disposed on a boundary between adjacent pixels in the first direction and a second part that is disposed within the third sub-pixel in one pixel, so as to limit a viewing angle of the third sub-pixel in the first direction, and

wherein the light shielding portion is not disposed between the first sub-pixel and the second sub-pixel.
